The normal micro-architecture of trabecular bone at the distal tibia is evident in an image obtained using FIESTA_C and parallel imaging at 7T (right) on a GE Signa.
The normal micro-architecture of trabecular bone at the distal tibia is evident in an image obtained using FIESTA_C and parallel imaging at 7T (right) on a GE Signa. Studies at this field strength by Sharmila Majumdar, Ph.D., and the musculoskeletal and quantitative imaging research group at the University of California, San Francisco, emerged as a consequence of studies at 1.5T. Images at 1.5T of a patient with osteoporosis demonstrate the degradation of trabecular bone indicative of disease progression, according to group director Majumdar. This work is establishing the foundation on which she hopes to build MR as a noninvasive biopsy tool for gauging the strength of bone in patients suspected of osteoporosis. (Provided by S. Majumdar)
Diffusion-Weighted MRI and Neoadjuvant Chemotherapy for Rectal Cancer: What New Research Reveals
September 3rd 2024In a comparison of imaging assessments to gauge the effectiveness of neoadjuvant chemotherapy for rectal adenocarcinoma, researchers found the combination of diffusion-weighted imaging and MR tumor regression grading had a 90 percent area under the curve (AUC) and a negative predictive value (NPV) of 93 percent.
New Research Highlights Emerging MRI Contrast Agent for Bladder Imaging
August 21st 2024A new MRI contrast agent may provide a viable non-invasive alternative for the detection of interstitial cystitis, according to preliminary research presented at the 5th International Consultation on Interstitial Cystitis Japan (ICICJ) in Kyoto, Japan.
MRI Study Offers Insights on Traumatic Brain Injury and Cerebral Microbleeds
August 19th 2024Detecting cerebral microbleed (CMB) in one of six healthy adults in a new study, researchers also found that CMB was the only MRI marker of small vessel disease (SVD) to be significantly associated with traumatic brain injury (TBI).
